Breakthrough in Nanotechnology: Researchers Develop Multi-Reconfigurable Nanodevices

Researchers at Mie University, led by Yuki Suzuki, have made a significant discovery in the field of nanotechnology. By utilizing structural nucleic acid nanotechnology, they have created multi-reconfigurable nanodevices that can respond to various external cues. These nanodevices are capable of transforming into distinct shapes based on combinations of pH, temperature, and the presence of specific ions.

The researchers developed a DNA origami lattice actuator, a complex structure composed of nine frames, each constructed from a rigid 4-helix bundle connected by flexible single-stranded DNAs. By modulating tetraplex formation through chemical cues and complementary suppressor strands, the shapes of individual frames are sequentially reconfigured, enabling the lattice actuator to adopt different configurations.
